"Wait a minute. I'm getting there. At first I thought he was too. The idea occurred to me first when I was talking to the priestess and she first mentioned that there were spies from Aptor. The coincidence of his appearance, that he had even managed to steal the jewel in the first place, that he would present it to her the way he did; all this hinted something so strange, that spy was the first thing I thought of, and I'm sure it was the first thing she thought as well. And she especially would think this if she did not know that Snake could read minds and broadcast mentally, because ignorance of his telepathy removes the one other possible explanation of the coincidences. But, Urson, why did he leave the jewel with us before he went to see her?" "Because he thought she was going to try and take it away from him." "Exactly. When she told me to send him up to her, I was fairly sure that was the main reason she wanted him. But if he was a spy, and knew how to work the jewel, then why not take it with him, present himself to Argo with the jewel, showing himself as an equal force, and then come calmly back, leaving her in silence and us still on his side, especially since he would be revealing to her something of which she was nine-tenths aware of already, and would watch him no more carefully than she would were it not confirmed." "All right," said Urson, "why not?" "Because he was not a spy, and didn't know how to work the jewel. Yes, he had felt its power once. Perhaps he was going to pretend he had it hidden on his person. But he did not want her to get her hands on it for reasons that were strong, but not selfish. "Here, Snake," said Geo. "You know how to work the jewel now, don't you; but you learned from Argo just now." The boy nodded. "Here, then, why don't you take it?" Geo lifted the jewel from his neck and held it out to him. Snake drew back and shook his head violently. Urson looked puzzled. "Snake has seen into human minds, Urson. He's seen things directly which the rest of us only learn from a sort of second hand observation. He knows that the power of this little bead is more dangerous to the mind of the person who wields it than it is to the cities it may destroy." "Well," said Urson, "as long as she thinks he's a spy, at least we'll have one of them little beads and someone who knows how to use it. I mean if we have to." "I don't think she thinks he's a spy any more, Urson." "Huh?" "I give her credit for being able to reason at least as well as I can. Once she found out he had no jewel on him, she knew that he was as innocent as you and I are. But her only thought was to get it in any way she could. When we came in, just when she was going to put Snake under the jewel's control, guilt made her leap backwards to her first and seemingly logical accusation for our benefit. Evil likes to cloak itself as good."
